Actually it was the Israeli air force that really made the difference, not their tanks. But as for Soviet military advice:
[i]Operation Stouthearted Men
By October 11, Bar-Lev and his division commanders (Generals Major Ariel Sharon and Avrahan āBrenā Adan, had constructed a plan to penetrate the Egyptian lines. Entitled āOperation Stouthearted Menā (Abiray-Lev in Hebrew), it took advantage of a key discovery Sharonās reconnaissance units had made: a major gap existed between the Egyptian defensive lines on the eastern bank of the canal, between 2nd and 3rd Army near Deversoir. In an apparent major planning error, the Egyptian unit which had defended that section of the line had been ordered north, with no unit ever being tasked to take its place. Standard Soviet war doctrine mandated unwavering obedience to the Central Operations Plan and provided commanders with as little intelligence as was necessary to complete their individual roles. This resulted in the commanders of neither 2nd nor 3rd Army ever bothering to verify the integrity of their flank, each assuming the gap had been filled by the other without bothering to inform them.[/i]

There is no ābetter optic and armorā inded in comparition with the contemporary ( at that time) soviet tanks.
And even the famouse 105 mm L701 in the mid-end of the 1960yy wasnāt so great agains the newest Soviet
115 -mm smooth-bore gun 2A46 ( T-62) and the 125-mm (T-64).
The SOviet shell had equal ballisic and penetration ability with more the explosive effect.
The what the Isreali really had better - the Western mass media symphaty and finantial support ( traditionally:) We all know why))And the better intellect over arabs ( also it was very fairly proved via the history)
Even the poorest Vietnamese and the Chinese were much better soldiers then the arabs with his Middle-East mentality :).
Um, the 105mm did just fine against Soviet armor. And I recall hearing or reading upon the Israeli invasion of Lebanon in 1983 that the M-60A1ās L7 gun could not defeat the newest T-72 operated by the Syrians, yet the Israelis had little trouble with them. Firstly, Iām not sure the armor penetration tables really say what you want them too as the Soviets tended to exaggerate the claims regarding weaponry. As for everything Iāve ever heard, the 100mm and 115mm Soviet guns were inadequate and to this day many nations have upgraded them by replacing the T-55s main armament with the L7 105mm gun.
In any case, the Israeli tanks, dug in, wiped out over 25% of the Egyptian Soviet made armor in a matter of hours. From the above Wiki Wiki Wiki link, a nice summation of what I stated before:
In the midst of this planning period, on October 14 the Egyptians launched a second coordinated offensive against the entire Israeli line from their strongpoints on the eastern bank of the Sinai. Personally ordered by President Anwar Sadat at the pleading of the thinly-stretched Syrians in the Golan Heights, and received with horror by his General Staff, the attack was a massive and near-suicidal frontal attack straight into the guns of the newly-buttressed Israeli defenses. Sadat made no pretense of attempting a breakthrough, but now sought merely to harass the Israelis and deny them any opportunity to reassign any of their (largely idle) Southern Front forces to the now-critical battles ongoing in the Golan Heights. In the largest tank battle since World War II[2], the Egyptian force of 1,000 tanks and 5,000 mechanized infantry faced 800 expertly dug-in and camouflaged Israeli tanks and their supporting infantry. By the end of the day, the Egyptians had lost 260 tanks and had suffered over 1,000 casualties. The Israeli losses were 8 tanks and 19 infantry. [3] This provided precisely the sort of disruption the Israelis needed. Operation Stouthearted Men was set to start at dawn, October 15.
I think the results speak for themselves, as the Egyptian forces, which had inflicted heavy casualties on the IDF in the days prior, now brokeā¦
